This dataset is about: Carbon and nitrogen data of surface sediment cores in the Canary Islands region. Please consult parent dataset @ https://doi.org/10.1594/PANGAEA.855462 for more information.
For 7 pelagic sediment cores, the decrease in unsupported 130Th activity with depth in the core was used to establish the mean accumulation rate over the last 300 000 years. Because CaCO3 is a Mn-free
